John Sayers' Recording Studio Design Forum

Hello GUY's

Its been a while but i have been side tracked by a few small projects but i have some finished pics to post in a few.

Glenn ,the room sounds amazing what i hear in room translate pretty dam good outside world.
i know the last time i posted i was trying to set up rew,but i just came accros a very helpfull video to
follow so i will post new pics and measure curves soon.

I have somewhat of a weak link in my isolation system which i have narrowed down to the garage on the other side of control room.See that wall only has 1/2'' gypboard and even though i beefed it up with 5/8'' gyp, i still get a slight sound from when there is a huge noise in garage which is my outer shell.
Funny thing is though i could be blasting the music in the studio and not hear a peep if i stand in the garage,so i know its weaker when sound travels from the other side which is from in the garage.But its small nothing to write home about,ill just maybe this summer add a layer or two of 5/8'' on that whole wall in the garage.

I have one last project i would love to build ,but i read on here and you guys don't recomend a DIFFUSOR on the rear wall in small rooms.

However i have a space in the rear of room where i want to build a QRD out of plexiglass so i could still get sunlight in.
RPG Makes them and my friend in NY has them in her studio and i am gealous

The space is 32 3/4'' by 58 3/4'' and i would like to get a cut sheet for the peices to asemble a QRD to fit it.

Any whooo i will be posting pics soon.

Thanks to everyone who helped ,Especially :Glenn ,Soundman 20/20 ,Xspace, and Mr Gervais.

And ofcourse Mr Sayer.

Well, you know the rule around here: "Pics or it didn't happen!".

Depends on several factors, but one of the issues is the lowest frequency that the diffuser is tuned to, and the distance between the device and your ears. The bare minimum is 3 full wavelengths of the lowest frequency from diffuser to head, but best is 7 or more wavelengths. (Don't forget that QRDs actually still affect frequencies one full octave below the lowest tuned frequency.) The issue is "lobing", or uneven spread of the reflected energy in both space and time. It takes a few wavelengths for that unevenness to smooth out a bit. You don't want your ears to be in lobes that are coloring the sound in one way or another. That's the main reason for the recommendation of not using QRDs in small rooms. Or if you do use them, then tune them so the lowest frequency they affect works out to more than 7 wavelengths from your head. (Of course, in small rooms that means that you have to tune them pretty high, which isn't very helpful...)

Can't wait to see the photos! And the REW graphs!

on the window you could make transparent slat panels (from 3/8" polycarbonate) like you did your wall units and angle them. we're doing that for a control room where the side angled treatments would block a window. congrats on the room!

Thanks Glenn, when you say angle it how are you talking?Its the window in th back of the room.

Do you have a crude drawing to show? and the place i get the glexiglass from said they could sit it for like $0.10 a cut,should i do some micro slots?
or should i do exactly like my slot wall sizes?

Thanks
